Application filed November 19, 1888. $eria1No. 291,19i. (No model.)

To all whom it may concern: other similar articles are to be burnished by Be it known that I, GEORGE B. KELLEY, replacing them on the cylinders or drums in a residing at Rockford, in the county of Winneverse position that is to say, while the bowl bago and State of Illinois, and a citizen of the and upper surface of the spoon is being bur- United States, have invented a new and usenished by the tool at one end of the burnisher 55 ful Improvement in Burnishing-Machines, of the back of a corresponding spoon will be which the following is a specification, referburnished by the tool at the opposite end of ence being had to the accompanying drawthe burnisher, so that however varying the ings, in whichlines may be the movements of the burnish Figure 1 is a plan view, the drums being ing-tools will be corresponding. 60 in section.

is a projection on the under side of the head m.

pis a plane portion on the bracket *6, on which the projection 0 slides, preventing the head m from turning.

q is a set-screw.

The operation is as follows: The knives, forks, spoons, or other articles to be burnished, E, are clamped on the cylinders or drums O, and are burnished by the burnishing-tools d of the burnishers B, which burnishers are reciprocated by the reciprocation of the rods A. The article E is clamped onto the cylinder or drum 0 by inserting its point in a recess near one edge of the drum 0, (see Fig. 1,) and by pushing the stem j inward until the handle of the article E is firmly held within the recess n of the head on and setting the set-screw g, which holds the stem j against retraction. The article is thus held against end movement by the set-screW-q, and is held against turning or twisting by the engagement of the projection 0 with the frame portion 19 of the bracket LI. When it is desired to .remove the article, the set-screw g is loosened and the spring Z retracts the stem j, releasing the article E. Each burnisher B is clamped to a reciprocating rod, A, at any desired point, according to the article to be burnished, by the set-screw in the boss at. The articles to be burnished-such as spoons and forks-are placed on the drums or cylinders, so that the burnishing-tool d at one end of the burnisher B will burnish the front or concave portion of the article, while the tool d at the opposite end will burnish the corresponding back or convex portion of a similar article, so that the movements of the tool-holders and tools will correspondthat is, while one is moving inward the other will move outward, so as to give the burnishing-tools an even pressure as the lines of the articles vary. The rings or collars h limit the inward movements of the tool-holders a, while the slots or grooves e and the pin f limit the outward movements and prevent the tool-holders c from becoming displaced. By this construction the face of one article and the back of another similar article can be burnished at the same time without giving any greater or additional pressure to projecting or higher parts, so that all parts of articles of irregular form can be properly burnished.

Suitable apparatus for reciprocating the rods A is shown and described in my said former patent; but other suitable apparatus may be used.

That I claim as new, and desire to secure by Letters Patent, is-

1. The combination of the tool-holders c c' and spring g with the tube 1), substantially as specified.

2. The combination of the tool-holders c 0, having the slots 6, with the tube 1), pins f, and spring g, substantially as specified.

3. The combination of the rod A, one or more tubes, 1), having a boss, at, the tool-holders c c, and spring g, substantially as and for the purpose specified.

4:. In a burnishing-machine, a cylinder or drum, O, in combination with a clamp, D, consisting of a bracket, '6, stem j, head is, spring Z, set-screw q, and head m, adapted to receive the article to be burnished, substantially as and for the purpose specified.

5. In a burnishing-machine, a cylinder or drum, O, in combination with a clamp, D, consisting of a bracket, 1', stem j, set-screw q, head m, adapted to receive the article to be burnished, and provided with aprojection, 0, and the plane portion p, substantially as and for the purpose specified.
